[ Method] Based on the sin-gle-factor test, the extraction factors of ethanol concentration, extraction temperature and extraction time were optimized using the response surface methodology with the extraction rate of chlorogenic acid as the response value. [ Result] The optimum extraction conditions of chlorogenic acid from sunflower meal were 57% of ethanol concentration, 39 min of extraction time, 53 ~C of extraction temperature, 100 W of ultrasonic power, 1 : 14 ( g/ ml) of solid-liquid ratio and one time of extraction. Under these conditions, the extraction rate of chlorogenic acid was 2.25%. [ Conclusion] Ultra-sonic assisted extraction method has high extraction rate but short time, the study provides a theoretical basis for the industrialized production of chlorogenic acid in sunflower meal.展开更多
